The **AD8567ACP-R2** is a high-performance quad operational amplifier (op-amp) manufactured by Analog Devices. It is specifically designed for applications requiring high output drive and low power consumption, commonly used in LCD gamma buffers and instrumentation. --- ### 1. Key Technical Specifications Below are the primary electrical characteristics of the AD8567: | Feature | Specification | | :--- | :--- | | **Number of Channels** | 4 (Quad) | | **Supply Voltage Range** | 4.5V to 16V (Single) / ±2.25V to ±8V (Dual) | | **Gain Bandwidth Product** | 5 MHz | | **Slew Rate** | 6 V/µs | | **Output Current** | ±35 mA (High Drive) | | **Input Offset Voltage** | 2 mV (typical) | | **Package Type** | LFCSP (Lead Frame Chip Scale Package) | --- ### 2. Core Features * **Rail-to-Rail Input/Output:** This allows the signal to swing very close to the supply rails, maximizing the dynamic range of the signal processing. * **High Output Drive:** Capable of driving large capacitive loads, which is essential for LCD panels. * **Low Supply Current:** Despite having four amplifiers, it consumes only about 700 µA per amplifier. * **Wide Temperature Range:** Rated for operation from -40°C to +85°C. --- ### 3. Pin Configuration (LFCSP Package) The "ACP" suffix indicates the **LFCSP_VQ** package (4x4 mm). Here is the functional layout: 1. **Inputs:** Each of the four amplifiers has an Inverting (-) and Non-Inverting (+) input. 2. **Outputs:** Four independent output pins. 3. **Power:** Single $V_{CC}$ (Positive) and $V_{EE}$/GND (Negative) pins shared by all four channels. 4. **Exposed Pad:** The LFCSP package typically features an underside thermal pad that should be soldered to the PCB ground for heat dissipation. --- ### 4. Common Applications * **LCD Gamma Correction:** Providing the reference voltages for LCD displays. * **ASIC Input/Output Buffers:** Interfacing between different integrated circuits. * **Portable Instrumentation:** Battery-powered devices requiring low power and high precision. * **Sensor Amplification:** Scaling and filtering low-level signals. --- ### 5. Part Number Breakdown The suffix **-R2** usually refers to the packaging and reel size: * **AD8567:** Base model number. * **ACP:** LFCSP package style. * **R2:** Small reel size (typically 250 units) or specific tape and reel format.
